"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"I highly recommend Josh Matus from SC Home Repair. We needed to have a ceiling replaced in a closet after it was damaged by water. The plumber who originally fixed the leak cut out the ceiling to fix the leak, but was not able to reinstall it. We hired Josh to replace the ceiling. He did an excellent job. He was punctual and polite, and kept me looped in on the entire project. He got my sign-off on all of his decisions and ran pricing by me when he needed to buy supplies. He knew exactly what he was doing. Josh finished the job quickly in two days and did excellent work while paying attention to detail. I would certainly hire him again!"

"My HVAC unit was 20 years old needed consistent repair, and my ducks where leaking. It was time for a new unit. I also wanted to relocate the condenser to improve my back yard space. I had gotten 4 quotes before someone referred me to http://www.aircmechanical.com/ Vitor was literally the first smart person to offer a quote. He suggested relocating the condenser to a side of the house and changing it to a suitcase type unit. He also came up with the creative solution of adding a 2nt inlet in another part of the house to reduce noise and improve airflow. The other contractors wanted to enlarge and or relocate the existing inlet which would have been an ugly mess. I now have an extremely efficient 2 stage unit installed correctly and he beat the other quotes. Entire product was completed in 2 days. I couldnâ t be happier."

"Working with Ross to install our Range Hood was an excellent experience. From the initial contact requesting an estimate for the work - to the installation itself - Ross was great. I would absolutely recommend him for your project and will contact him again if we have future needs for an electrician."

Heating and Air Conditioning questions, answered by experts

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.
